COMBINED GAS AND COAL RANGE.

T0 all whom it may concern-.-

Be it known that I, CHRISTOPHER F. CODA, a citizen of the United States of America, residing at Detroit, in-the county of Wayne and State of Michigan, haveinvented certain new and useful Improvements in Combined Gas and Coal Ranges, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to combined gas and coal ranges and has particular reference to a construction of oven which is adapted for heating with the alternative fuel.

In the drawings: Figure 1 is a plan view showing the oven bottom and relative arrangement of the fines; Fig. 2 is a vertical section; and Fig. 3 is a cross section.

In the construction of coal ranges, it is usual to pass the products of combustion first over the top of the oven and then down ward at one side and beneath the bottom of the oven to the flue at the back. To secure a proper circulation of the gases beneath the oven a deflector is usually placed in the flue which compels circulation toward the front before the gases are permitted to escape to the rear. With my improvement, I have utilized the space necessary for the forming of the bottom flue of the oven for holding a gas burner, which is thus located in a pocket where it will not interfere with the space of the oven.

As shown A is the oven chamber having the fire box B at the front thereof, the top flue C passing above the oven and connect ing with the down-flue D at the rear thereof, while beneath the oven is a flue space E connecting with the rear flue F.

At A there is provided an outlet whereby gaseous products of combustion may escape from the oven to the rear flue.

G is a niche or pocket formed in the bottom of the oven and extending down into the flue space E. In this pocket is located a gas burner H which extends out through the rear and is provided with a suitable gas mixer I.

To avoid interference with the function of the stove when operated by solid fuel, the pocket G is formed by a hollow member J which is placed between the bottom plate K and the oven and the parallel plate L which forms the bottom of the flue. This hollow Specification of Letters Eatent. Patgnt ed ljsgg, 14 1915 Application filed March 3, 1914. Serial No. 822,117.

member J is preferably arranged diagonally across the bottom of the oven in such position as to form the deflector in the bottom flue space, which directs the products of combustion toward the front before permitting their escape. -W hen the stove is used with the solid fuel a lid M may be used to close the top of the pocket, but when the stove is operated by gas fuel,-this lid is removed. To distribute the heat a deflector plate LT is arranged parallel with the oven bottom, being supported by legs 0,. and preferably having a portion P of increased thickness arranged directly opposite the burner.

With the construction described in operation, when. the stove is operated with solid fuel the gaseous products of combustion will pass successively through the fiues C, D and E, being directed in the latter flue by the hollow deflector forming the pocket G. When, on the other hand, the stove is operated by gas fuel, the lid M is removed from the pocket and the deflector plate N is placed in the oven, which will distribute the gaseous products from the burner.

What I claim as my invention is 1. In a combined coal and gas range, the combination with an oven casing having a bottom flue, of a hollow member within said flue extending diagonally forward from one end of the flue walls and terminating in a spaced relation to the front flue wall, said member having its top opening into the oven and having its bottom closed, and a burner pipe within said hollow member passing out through the rear end thereof, the gases of combustion passing through said flue being deflected by said hollow mem her to pass between the same and the front of the flue.

2. In a combined coal and gas range, the combination with casing, of an outlet flue connecting therewith, an oven within the casing, a fire box at one side of the oven, a flue extending from said fire boX over the oven, and down at the other side of the oven, and beneath the oven to the outlet flue, a hollow member within the bottom flue forming a deflector for the products of comstove and extending diagonally rearward 5 side fine and through the adjacent side Wall '7 of the teve casing. 7 v
